lightningterror cdb886a454 GS-hw: Implement missing st_int shader bit. 
Was causing bad shader errors in GT4.
 2022-10-24 16:22:44 +02:00
lightningterror abcbdc4a25 GS-hw: Further improve how we handle blend mix 1. 
Compensate slightly for Cd*(As + 1) - Cs*As.
Try to compensate a bit with substracting 1 (0.00392) * (Alpha + 1) from Cs.
The initial factor we chose is 1 (0.00392) as that is the minimum color Cd can be, then we multiply by alpha to get the minimum blended value it can be.

TellowKrinkle 1ad6605dfb GS:HW: Remove comment on rgba to 8i only-blue optimization 
Doesn't seem to improve anything anymore (GPUs do this with csel now anyways, it's like 5 instructions with no divergence)

refractionpcsx2 92cd6e8435 GS: Fix DX shader error 2022-10-09 04:53:18 +01:00
TellowKrinkle 0637682eb0 GS:HW: Properly handle fbmask of negative values 
Previously was possible with blending and colclip, but now more common with the new hdr algorithm
 2022-10-09 04:06:59 +01:00
TellowKrinkle 73ae9f8879 GS:HW: Make HDR algorithm more float-precision-friendly 
- Use whole numbers instead of 255ths
- Use range -128 - 127 instead of 0 - 255 for accumulation blends
 2022-10-07 20:44:53 +02:00
TellowKrinkle 1b34eb14f8 GS: Pass through primitive ID in geometry shaders in DX12 and VK

 2022-09-06 21:07:56 +02:00

TellowKrinkle 91601e5647 GS: Manually do bilinear sampling when converting RGBA to depth 
Shader bilinear doesn't properly handle the case where r overflows into g (or g overflows into b, etc)

TellowKrinkle 882c09b870 Vulkan: Format convert.glsl 2022-08-20 10:12:24 +01:00
refractionpcsx2 5447da0588 GS: Don't do blend_mix on HDR 2022-08-16 20:54:55 +01:00
refractionpcsx2 1b18e02fe0 GS: Add constant adjustment in blend mix when reverse subtracting. 2022-08-16 20:54:55 +01:00
TellowKrinkle cb64e8d504 GS:HW: More accurate blend equation for blend mix 2022-08-13 00:01:23 +02:00
lightningterror 6b48cf574d GS-hw: Adjust how we handle specific blend mix cases. 
Replace Cs*As + Cd*(1 - As) with Cs*As - Cd*(As - 1).
Replace Cs*F + Cd*(1 - F) with Cs*F - Cd*(F - 1).
As - 1 or F - 1 subtraction is only done for the dual source output (hw blending part)
since we are changing the equation.
Af will be replaced with As in shader and send it to dual source output.

Also check if A*Alpha in the shader overflows, if it does then adjust the
alpha that is sent for HW blending further to compensate.

lightningterror b8236b1b1c GS-hw: Partially revert #5540 
Allow to wrap on colclip.
For real tho, ideal solution is sw blend, doing any clamp/wrap is wrong on blend mix.
 2022-02-19 00:38:13 +01:00
lightningterror 1a3d77b2c0 GS-hw: Fix d3d11 depth sample shader. 
Also adjust some comments to match updated shader names.
 2022-02-18 19:21:01 +01:00
lightningterror 06766ddb98 GS-hw: Don't wrap on 16bit destination format for blend mix. 
Helps Dog's Life blending, we shouldn't wrap as we do more blend math afterward which will be wrong if we wrapped before.
 2022-02-18 19:00:54 +01:00
lightningterror 7151848406 GS-hw: Rename alpha_clamp to blend_mix. 2022-02-18 19:00:54 +01:00
